What Cookies Does Gransino Use?
Short answer: three types. One group keeps the site working. One counts visits anonymously. One tags clicks when you head out to a casino. Nothing sneaky, nothing hidden — every single cookie named below with its lifespan and whether you need to say yes first. Written to match UK PECR and UK GDPR rules as the ICO applies them.

1. So What Actually Is a Cookie?
A cookie is just a short text string your browser stores locally when it loads a web page. That's it. It can't run code on your machine, install anything or read your other files. The point is memory — knowing you've already answered the consent prompt, keeping a session open as you click from page to page, or counting anonymous visits.
UK PECR and UK GDPR together set the ground rules. Any cookie that isn't genuinely necessary for the site to function needs your active agreement before it lands on your device. The ones that are genuinely necessary don't need that step, but we list them anyway so you can see exactly what's there.
2. Three Groups — That's All
Gransino uses exactly three groups of cookies. Here's what each one does and whether you get a say in it.
- Site cookies — the bare minimum the website needs to stay functional. Keeps your session alive, holds your banner answer, protects form submissions. You can't turn these off without breaking things, and PECR says we don't need permission for them.
- Measurement cookies — Google Analytics running with IP truncation on. We see aggregate data: which pages are popular, roughly how long people spend, where traffic comes from. No individual records. Requires your opt-in.
- Referral-tracking cookies — set when you click a
/gooutbound link to a casino. They stamp the click so the operator knows the visit came from us, which is how we get credited for the referral. Requires your opt-in.
3. Every Cookie, Listed
The tables below cover every cookie Gransino is capable of placing on your device — name, purpose, how long it lasts and whether we need your permission. We update these tables the same day anything changes.
Table 1 — Site Cookies (Always On)
These cookies power the basics. Without them the site can't hold a session or remember your consent answer. PECR regulation 6(4) exempts them from the consent requirement; we list them here regardless.
| Cookie name | Purpose | Retention | Consent |
|---|---|---|---|
PHPSESSID |
Standard PHP session identifier — keeps you logged into the same session as you move between review pages and comparison tables. | Session (gone when you close the tab) | Not required (site cookie) |
grx_consent |
Saves your answer from the cookie pop-up. Without this, the banner would appear every single page load. | 11 months | Not required (site cookie) |
grx_csrf |
A short-lived security token tied to form submissions that blocks forged requests from other sites. | Session | Not required (site cookie) |
Table 2 — Measurement Cookies (Opt-In)
We run Google Analytics 4 with IP truncation on. None of these cookies touch your device until you give the go-ahead. What we get back is aggregate: page views, rough session lengths, referral sources. Never linked to a name or email.
| Cookie name | Purpose | Retention | Consent |
|---|---|---|---|
_ga |
Assigns a random ID to your browser so Google Analytics can distinguish separate visitors — no personal details involved. | 21 months | Required (opt-in) |
_ga_<container-id> |
Keeps track of session state and campaign source for the GA4 property this site reports to. | 21 months | Required (opt-in) |
_gid |
Groups visitors by day so we can see how many unique browsers land on a page within a 24-hour window. | 24 hours | Required (opt-in) |
_gat |
Puts a cap on how frequently analytics pings are sent from high-traffic pages to avoid data overload. | 1 minute | Required (opt-in) |
Table 3 — Referral-Tracking Cookies (Opt-In)
Click any /go link heading to a casino and two first-party cookies get written that record the click origin and which page or campaign sent you. That's how the operator knows to credit the referral if you open an account. No personal data — just an anonymous click stamp.
| Cookie name | Purpose | Retention | Consent |
|---|---|---|---|
grx_ref |
Records that the outbound click came from Gransino, giving the operator's system what it needs to credit the referral to us. | 45 days | Required (opt-in) |
grx_campaign |
Stores which page or campaign the click came from, used only for our own internal traffic reporting. | 45 days | Required (opt-in) |
4. The Consent Banner — How It Works
First visit, a banner appears at the bottom of the screen. It names the three cookie groups and gives you three clear options:
- Accept all — turns on site cookies, measurement and referral-tracking in one go.
- Reject non-essential — only site cookies stay active; measurement and referral-tracking are blocked.
- Manage preferences — choose measurement and referral-tracking separately.
The banner follows the ICO's rules: the "reject" option is just as prominent as "accept", nothing is ticked for you, and no measurement or referral cookie fires until you've actually made a choice. That choice is saved in the grx_consent cookie. Change your mind anytime by hitting "Cookie settings" in the footer.
5. Controlling Cookies in Your Browser
Your browser has its own cookie controls that work independently of anything on this site. Here's where to find them:
- Google Chrome — Go to the three-dot menu, pick Settings, then Privacy and security, then Third-party cookies.
- Mozilla Firefox — Hamburger menu, Settings, then the Privacy & Security tab, look for Cookies and Site Data.
- Apple Safari — On a Mac: Safari menu then Settings, Privacy tab. On iPhone/iPad: iOS Settings app, Safari, then Privacy & Security.
- Microsoft Edge — Three-dot menu, Settings, Cookies and site permissions, then Manage and delete cookies and site data.
Want to block Google Analytics everywhere, not just here? Install Google's own opt-out extension at tools.google.com/dlpage/gaoptout — it works across every site. For a plain-English overview of your cookie rights in the UK, the ICO has a dedicated page at ico.org.uk/your-data-matters/online/cookies.
6. Cookies From Casino Sites Are Nothing to Do With Us
The second a /go link drops you onto an operator's own website, you're on their turf. Any cookies they write from that point are covered by their cookie policy, not ours. Gransino has no way to see, read or touch anything an operator stores on your device.
Worth reading the operator's own cookie notice before you sign up. Most casinos use marketing cookies, fraud-detection cookies and session cookies under their own domain, and the rules governing those — retention periods, consent flows — come from whichever regulator issued their licence.
7. What Actually Happens If You Say No
It depends which group you're blocking:
- Site cookies — you can't really block these without breaking things. The session won't hold and the banner will pop up again on every page.
- Measurement cookies — zero impact on what you can do here. All the reviews, tables and ratings work exactly the same. We just don't receive any anonymous data about your visit.
- Referral-tracking cookies — the operator may not be able to connect your visit to Gransino. That won't change any offer you're entitled to from them; it just means we might not get credited for sending you.
8. Keeping This Page Up to Date
We update this page whenever a cookie is added or dropped, and we do a full check at least once a year regardless. The "Page refreshed" date at the top tells you when we last touched it. If something significant changes — a new third-party data processor, say — we'll also post a notice on the homepage and show you the banner again so you can make a fresh choice.
